An Innovative Thermoplastic Coating For CUI Applications

An innovative thermoplastic coating for CUI applications
Available for download

An innovative thermoplastic type of coating material based on pure isobutene homopolymer was investigated to determine whether it would be fit for purpose in CUI services at low and moderate temperatures up to 120 °C. This polymer is commonly called Polyisobutene (PIB) and has a unique set of properties that are beneficial for protecting metallic structures from corrosion. Polyisobutene is a polyolefin with a chemical structure similar to Polyethylene (PE) and Polypropylene (PP). One of the major differences is that PE and PP are solid materials with a high degree of crystallinity, whereas PIB does not have a crystallization or melting temperature. PIB has a glass transition temperature (Tg) below – 60 °C which indicates that the polymer is a liquid above this temperature.

Corrosion Under Insulation (CUI) typically occurs on thermally insulated pipes. A systematic approach is needed to minimize the risk of CUI, and part of this approach is to choose coatings that protect the pipe from corrosion and can resist the often aggressive environment with insulated pipes. Presented is an innovative thermoplastic type of coating material for CUI purposes that can be used for both newly constructed pipes and coating repair. Presented are the technical assessments that were carried out to evaluate performance under CUI conditions, including tests as specified in various industry standards like ISO 21809-3 1 (e.g. accelerated ageing tests), ISO 12944-9 2 (corrosion at scribe), and additional customized tests including resistance to hot dry/wet cycling including thermal shock, and freeze/thaw cycling. Furthermore, a study was conducted to determine the capabilities of arresting pit growth in stainless steel. From these test it was concluded that these type of coatings are potentially suited for use in CUI service conditions up to temperatures of 120 °C.

Aesthetic Issues With Spray-Applied Fluoropolymer Coating System

A building, partially clad in fluoropolymer coated aluminum panels, was observed to have an aesthetically unacceptable appearance while still under construction. Once installed on the building, many of the panels exhibited a vertical streaked appearance under certain conditions. When the panels were at ground level, or when the sun was bright, the streaky appearance was not noticeable. However, in conditions of low light, such as during early morning, dusk, or on cloudy days the streaky appearance was reported to become apparent. A visual mock-up, consisting of multiple coated panels that had been approved by the architect as a guide to the anticipated appearance were also present on-site as a reference. This visual mock-up was used as a reference for acceptable appearance of the coated panels.

It is fair to say that maintenance in the worldwide oil and gas industry has changed dramatically over the past ten years.  Facility owners are more than ever looking to reduce shutdown times, to improve plant efficiency and to extend plant lifetimes. With this comes the increased industry understanding about corrosion under insulation (CUI) with its deleterious impact and the ongoing desire for pragmatic high performance and cost-effective coating solutions.

Corrosion of reinforcing steel is the most significant cause of deterioration of reinforced concrete structures. Exposure to de-icing salts, seawater and chloride-containing set accelerators can play a significant role in reinforcing steel corrosion. Long-term exposure to carbon dioxide is also cited as a contributor to the corrosion of steel in concrete as well.
